Sensor-NITE bought our ALM for bench testing

Sensor-NITE North America, bought an ALM kit from us to do bench testing. This is an endorsement to our professional designed accurate lambda meter. Sensor-NITE is known for diesel exhaust aftertreatment technology and high-temperature sensors. ALM is certainly a good choice for them to measure the AFR for diesel applications. As you know, LSU4.9 has the capability to measure the wide range of AFR and does not need to re-calibrate frequently. Especially the combinations of LSU4.9 and CJ125 make our ALM is very accurate for lean AFR measurement, which is vital for diesel engine applications.

Power-Base INC bought 6 ALM units for their biogas/diesel flex fuel engine applications

Powerbase Energy Systems INC, ordered 6 ALM units and had installed and integrated them with their biogas/diesel flex fuel engines in the fields. The ALM has been proved working seamlessly with their engine control systems, and feeding back the AFR (lambda) accurately and responsively. It has become a vital part of their systems to control the engines and run the engine stablly. Powerbase Energy Systems Inc. is a full service provider of biogas power generation systems and anaerobic digesters designed to meet the organic, climatic and economic conditions of North America

Finnish Drag-racing tuners compared the ALM and LC-1's analog outputs

Finnish drag-racing tuners Sami and Petri bought an ALM and compared the ALM analog output with LC-1 analog output.

As you can see from the above oscilloscope:

1) LC-1 can only reach about 1.28 lambda when it's lean; and can not measure the leaner mixture; while ALM can measure the leaner mixture with the lambda all the way up to 1.51 (reaching the limit of user setting 3.3V), and then becomes flat.

2) LC-1 is only responsive between about lambda = 0.7 and 1.3; where it can stay close to ALM. Out side of this range, it does not respond any more.

3) Because the resolution of the scope setting is not small enough, (1s/Div, and 0.75v/Div); it is not able to tell the big difference of response time between the ALM and LC-1.

4) You can tell LC-1 has more noise than ALM, even with a rough resolution of the voltage setting. Especially at the end of the traces, LC-1 has some spikes that are obviously noises.
